an off-road H-pipe will help your top end AMAZINGLY..
it'll move stock peak from 4200 rpm to closer to 4500rpm..
and add about 12 rear wheel HP.. (in my case, I did plugs, wires, h-pipe, timing bump) and it all helped my top end, and now I run 96 mph in the traps (over a 3 mph improvement) and my times went down...

I don't think that's too shabby considering I have a stock heavy 94 w/ 3.27's, h-pipe and pulleys..

so yeah, get an h-pipe.

but on the other hand, cold-air kits really don't help much, if you want to increase your breathing, and you know you'll go with heads, cam, intake in the future, get a bigger MAF/t-body combo, like a 65mm t-body with a 76mm MAF by C&L with their own cold-air kit included..

good luck
